A fourth meeting between former UFC champions Tim Sylvia (31-7) and Andrei Arlovski (17-9) is set for “ONE FC: Pride of a Nation.”

Company officials announced the heavyweight clash earlier today.

The event takes place Aug. 31 at Smart Araneta Coliseum in Quezon City, Philippines, and it’s available as an online pay-per-view in North America.

It’s Sylvia’s first booking since the 36-year-old recently was offered a Strikeforce contract and a fight with Daniel Cormier that was later rescinded. Sylvia recently told MMAjunkie.com (www.mmajunkie.com) he was “shocked” that the contract, which would have allowed him to move into the UFC after the Strikeforce fight, was ultimately scrapped. The UFC’s Frank Mir got the slot against Cormier instead.

As a consolation, Sylvia now fights Arlovski for a fourth time. Seven years ago, they were the two biggest names in the UFC’s rather shallow heavyweight division. Arlovski won the first meeting via submission to win the interim title, but a year later, Sylvia won the next two fights to first take and then defend the belt.

Lately, Sylvia has been busy on the regional circuit. Fighting at heavyweight and super heavyweight, he’s won seven of his past eight fights, six via stoppage.

The 33-year-old Arlovski, meanwhile, snapped a four-fight losing streak a year ago and since has posted back-to-back knockout wins over Ray Lopez and Travis Fulton. Prior to the needed wins, he suffered three knockouts during a string of four losses to heavy hitters Fedor Emelianenko, Brett Rogers, Antonio Silva and Sergei Kharitonov.

Arlovski initially was slated to fight Soa Palelei at ONE FC 5, but the Australian told MMAjunkie.com the fight was scrapped when he refused to sign a five-fight deal with the promotion.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
